End of Service for the Weather Underground API

We’re contacting you today to tell you about some upcoming changes to the Weather Underground (WU) API and what these changes mean for you.

The WU API has been around since 2010 to help you develop apps and websites as well as manage your Personal Weather Station data. During that time, we’ve watched you build amazing products and visualize weather data with creativity and purpose.

Over the years, our infrastructure has struggled to keep up with the growing numbers of users coming to us for API data. We realized we needed to make changes to ensure the highest level of quality, performance and uptime for our API users.

As a result, we’ve made the difficult decision to retire the Weather Underground API. The Weather Company, which acquired WU back in 2012, offers a powerful suite of enterprise-grade APIs that might be better suited to meet your scale and performance needs while offering a broader range of weather data. You can see these products here.

Here’s what you need to know going forward:

Your subscriptions, and therefore access, will continue to work through 12/31/2018.

If you are a paying WU API customer, you will receive a call from a representative from The Weather Company, and IBM business, to discuss transition options to other API services. If you’d like to have these conversations sooner, contact us.

If you are a Personal Weather Station owner, you will receive more information about our plan to offer free access to the data you provide to Weather Underground. We’ll reach out once that plan has been finalized.

The WU Forum will continue to be the best place to connect, keep you informed, share your feedback and get your questions answered as we go through this process.

We are grateful for your commitment to Weather Underground and appreciate your understanding and support as we work through this process. These changes will allow us to continually improve our services and develop new features to keep WU a thriving place for you for many years to come.

"If you are a Personal Weather Station owner, you will receive more information about our plan to offer free access to the data you provide to Weather Underground. We’ll reach out once that plan has been finalized."

Personally I am not worried about getting history of my data I send to you. it is written to SQL on my site as well.

I think most PWS users that run a site would like to know if you could confirm there will be a forecast offered via API to PWS Owners or not?﻿

Me too. I send you realtime weather data (about once a minute) and in exchange I get five day forcast data refreshed about once an hour, and weather radar animations about every five minutes. If I can't get that, then I have no reason to continue to send you data.

As mentioned elsewhere, PWS owners who send their data up to WU will have uninterrupted access to their data, and a limited range of other information, like forecasts, through an API that is being developed. The shift to the new API will likely occur after the first of the year, so for PWS holders, access to the WU API will continue past December 31 while we prepare for the transition. So PWS uploaders are is a special, protected class right now.

This shift is so that we can provide access to a better, more modern infrastructure. I'm pretty sure that's not nothing. Your data can be viewed by your community easily on a platform that's used worldwide. I'm pretty sure that's not nothing, either.

Whether you personally find value in it is a decision only you can make.

Hello Victoria, the main reason why we are sending to you our data for free and not on a limited basis is to get weather forecasts from these data and from data of other uploaders for use as service to our community. We don't need access to our own data because we have them in the first place. What we are concerned right now is the limited access to the forecasts which were mainly based on the consolidated data from the uploaders like myself. Also the uncertainty of how the whole system of sharing the information and the new API will take form are putting us on the edge of our seats because this will greatly affect how we will deliver our services to our clients as well starting 2019 and time is running out to prepare for this. BTW, we also spend time and money to maintain these PWS, 20 of them scattered all over the Philippines in my case. The PWS had evolved from being a hobbyist thing to a great resource for a country like the Philippines visited by an average of 25 strong typhoons every year and expected to increase and become more frequent and stronger due to the effects of climate change. On the other hand, we are your great resource in generating these valuable forecasts. So please do not kill the goose or geese that lay the golden eggs.

If you are delivering services to clients, then you might consider looking into moving to The Weather Company's API, and not sitting on the edge of your seat waiting to see what you might be getting for free.

It sounds as if you already see the value of our aggregating and incorporating the data into forecasts. That doesn't come free on our end, either.

PWS owners will be able to continue to use the WU API past the December 31, 2018 cut-off which will affect all other users who have not made prior sales contracts with TWC/IBM. PWS owners will subsequently have time to shift their calls once the new API is up and running. That is what we are doing in an effort to work with the many PWS uploaders who see the value in putting their data where large numbers of people can see and use it.

But things are not ever going back to the way things were before. Abundant free data on a global scale is just not possible. It was clearly unsustainable, or we wouldn't be here now.

I'm glad you're finding the Weather Underground useful, and I hope you will continue to do so.

Well no, it is not that it was unsustainable, it was that IBM bought the data stream by buying the aggregator. Perhaps a new open community will form around the PWS community, and cut IBM out of the data stream, perhaps not.

But let's not pretend it was because anything was "unsustainable"

"Abundant free data on a global scale is just not possible."

PWS data is compact. It's a tiny amount of data, and on a global scale is easily possible, and has been free at least since I used to upload it on a 300 baud modem.The proof of this fact is that IBM will be continuing to host the data for PWS owners at no cost.

To an extent, I agree with Victoria concerning "free" data. To anyone who is not a PWS provider, there should be no "free", except for developers which would be low use. If some is out there commercially creating an application using this data, they should pay for it's use. However, if it is a PWS owner, and their data is good, they should have access to their data and more at no cost, within reason. Within reason is subject to interpretation, but I would expect all my data, and weather data/maps/forecasts within my region, but that's something that could be discussed. However, it appears that what you will get is your data, and just a bit more.

Overall, I don't think IBM/WU wants to really continue the relationship with the PWS owners. Look at everything that has happened since the take over by IBM. Look at the tone set in this forum. And what about these statement from them... So PWS uploaders are is a special, protected class right now . Is this special protected class permanent...or just for the near term? Another member asks Are individual weather station owners important to WU's business, ﻿﻿response, were not going to discuss this. If you read though this forum, I don't think they really need to answer, the answer is there without saying any written statement from them.

At this point, the best thing that could happen is that another company sees the value of the contributors of personal weather data and starts developing or expanding their own PWS system.

agree with Guy here. look at flighradar24 or flightaware: ADS-B providers, equivalent to PWS owners for WU, provide their data in return for an enterprise subscription at zero cost. supplying free data equals free data in return, especially when you're whole network is built on that free data. it doesn't mean a tiny amount of free data, or "hey you can view your own data," it means "we will provide PWS owners with the full set of tools we provide paying customers."

Victoria, I know you work for a behemoth company that is about the bottom line, but since you're representing IBM here, you should work to make sure your leadership doesn't burn the bridge. your team needs to get transition information and new API info out to PWS owners ASAP. you won't get a second chance with PWS owners once they move on to another provider.

Nobody is expecting abundant free data. Indeed, the existing WU API doesn't provide "abundant free data"... think there was a daily quota of only (IIRC) 500? ... can't find the pricing structure because it has gone. It was a chargeable service. Just like darksky and openweathermap, who also have a low free quota for testing and hobbyists.

> It was clearly unsustainable, or we wouldn't be here now

I really don't buy this line of argument. See above. The WU API was a paid service. The pricing structure could have been tweaked if it wasn't quite working, e.g. to reduce the free quota, and/or increase the cost. Surely if darksky can manage it, IBM can too? Dang, hand me the reins to the WU API and I could manage it myself... cloud servers are two-a-penny nowadays.

No, pure and simple this is a business decision from some suit in IBM somewhere. Something along the lines of "we have the TWC API for which we can charge big business rates; the WU API is merely taking business away from our cash cow TWC API".

I'm not a PWS owner myself, though I've often toyed with the idea, but I suspect that part of the ethos of a large majority of these people is that they take satisfaction in providing data -- along with thousands of others -- to provide a valuable resource for all. They don't want this to be some sort of "private members club" where only PWS owners have ongoing API access. It's like open-source developers wouldn't want access to their libraries restricted only to other developers who themselves are open-source developers.

The end result of this is, I suspect, that these PWS owners will drain away from WU and send their data to something more community-minded and less corporate.

But maybe that is what IBM wants. Shut down the competition and disrupt.

Maybe something else will rise to take over the space where WU used to be... I certainly hope so.

"Victoria, I know you work for a behemoth company that is about the bottom line, but since you're representing IBM here, you should work to make sure your leadership doesn't burn the bridge. your team needs to get transition information and new API info out to PWS owners ASAP. you won't get a second chance with PWS owners once they move on to another provider. "

Mr. Spitler, I'm really not sure what you're talking about here. I am doing everything in my power to provide accurate information as soon as it's possible. That PWS owners are, as a group, being provided access beyond that offered to anyone else, to me that suggests that we are doing what is possible to facilitate a difficult shift for everyone.

I said that PWS owners would be a protected class "for now" because once they are the only class, they are all protected by default. I have no information whatsoever of PWS owners being shut out in the future.

PWS owners who are uploading their data will have uninterrupted access to their data, and a limited range of additional items. They will be able to access up to 1000 calls per day and 30 calls/minute. (This reflects an increase over what I mentioned before, which was the base level for the WU API.) When the API for the PWS uploaders is ready, we will provide a transition period to switch from the WU API to the new API. For PWS uploaders, the Weather Underground API will ﻿not﻿ close down on December 31.

For everyone else, and yes, this includes the many people with developer keys, the Weather Underground API will close down on December 31, 2018, unless they have made a prior contractual arrangement with IBM/The Weather Company.

Thanks for the clarification and I'm glad that PWS owners are being "protected" in that we won't be forced onto something new by 31DEC, but my concern is the general lack of trust in the powers that be (IBM) with regard to providing us with a proper path forward. As others have pointed out, "any day now" has turned into absolutely no additional information. My point as I was pointing out is simply this: in the event of no further information on a change that has been accounted for "months" (as you stated below), PWS owners such as myself will lose trust in IBM/TWC to provide something and move on to (or create) another platform.

I hear you. I am doing the best I can. I can understand how that could be interpreted as you have.

But I would like to point out that even when I don't have additional information, I am constantly answering posts. Which might add to the feeling you're not getting anything new, but it's different from, I think, not providing anything. You (the big collective you, not necessarily Christopher personally) have my email, you can poke me for updates. I remind you (again, the big collective you) of this just to say that I am not (I have no reason to believe!) going up in smoke on the 31st of December. It doesn't mean I will have information any faster, but you will continue to have it when I have it.

Thanks, Victoria. And same for you, it's the "collective you" being IBM. Most of us really like WU as it has helped people, organizations, and global communities alike. It's really astounding to read these comments and realize that my measly PWS is a small part to a global group of people who use PWS and data from your site to support functions we consider "basic" in other parts of the world. We understand change has to come (well, I do) but having proper advance notice is key. My personal "gripe" is that we know change is coming, but we don't know anything more and it's been quite some time since the announcement.

Either way, thanks for actually reading and responding to posts, that's more than most organizations do!

What is the tecinal reason for changing the api if you want to change the quotos just change them. you have not explained why you need a new api other than to kick off all current users. Any changes you wish to make coukd be backward compatable to the existing api. So whats the deal..
..

My frustration with WU is that we were never informed that this change was coming. We are billed by WU, so I know that they have our contact information. I stumbled upon a notice shortly before the holidays that the API would cease function at the end of the year and had to write a script to stop displaying weather data throughout our network of screens across our 3 campuses as of Dec 31, 2018. Now I come back and hear that the API is still working, but for undefined amount of additional time. It is extremely difficult to make decisions regarding how to proceed when information is not forthcoming. From what I understand, we would need to rewrite our scripts for a possible new API at some point in the future. Is this correct? With so much uncertainty, I'm not sure why I shouldn't just switch to another feed such as Accuweather now. Anyone have any thoughts on that?

WU is no longer a site for weather enthusiasts and amateurs. It's now a purely commercial for-profit advertising platform. The community they used to serve has been kicked to the curb by IBM and it's pure profit motives. Shame on the old WU for selling out. I've already shut my station down. It's pointless to continue here. I don't make you money, so I'm not important anymore.

I just joined! It looks like I am moving to Windy Weather or Accuweather or any weather station that appreciates the money I spent and the free data that I am providing to you! Thanks for nothing Darl!

Hi, my subscription changeover worked fine. I just moved to South Carolina. My station is KSCLONGS15. The coordinates are correct. I’m at about 30 feet in elevation. My WS-1200 shows the correct pressure. Wonderground and the PWS app show pressure almost 0.50” higher. When I go to wunderground and find my station settings it shows my elevation of over -107000! I’ve emailed twice under customer support and no one answers back. Help please

Yes, we expect to have basic forecast data included in the API offering for PWS owners. Can you let us know what your needs are for forecasts? We want to focus strongly on the needs of PWS owners for this new API.

To be usable for weather hobbyists, it needs to be:1) free for low-volume queries (< 100 api accesses per day)2) provide essentially the same data as provided by the current API for a 10-day forecast query (day/night needed .. hourly not needed).﻿

the big concern i have is the integration ability for my home automation. control4 has a driver to pull API data, and as i run a PWS, i need the data from it into my automation in order to calculate certain values and make certain decisions. are you working with partners like control4 to ensure this is done?

Most of the data I receive directly from my weather station, but the current conditions and forecasts (daily and hourly) would still be useful for my existing projects (landscape automation, local trends, pattern analysis, etc.). I have been supplying my weather station info to weather underground for 10 years now, so I'd be sad to see any of the forecasting disappear.

I can do without the rest like alerts, geolookup, astronomy, tide, yesterday...pretty much everything I can do without except for forecast and hourly!

Very few people are looking for their own data back. I have a decade's worth of data, I can use that all day long.

What everyone is looking for is enriched data, that's the value add. I don't believe just my immediate forecast for my "microclimate" (to misuse a word) is all that valuable. For the DC area, for example, I would expect to be able to pull forecasts for the region.

Since you Weather.com offers 5/10 day and hourly forecasts for specific areas, I would hope to be able to access similarly enriched data.

@Tom I'm in the same boat. I purchased my weather station (Davis Vantage Pro2) back in 2008 and have archived every piece of data with no interaction from Weather Underground. So I agree, no need for regurgitating data I already have at the cost of bandwidth, lol.

However, forecasting is something our weather stations are very hit or miss at and where that data from weather underground is quite valuable. Beyond the automation and analysis I run, I also maintain public and federal trails and having a local forecast (daily and hourly) has been very beneficial. The symbiotic relationship between Weather Underground and the PWS owners has been win/win and I hope we can still share our plentiful data with them in exchange for forecasting api calls.

The most important thing for me is to be able to have my Amazon Alexa and Google Home devices respond to my requests for current conditions at my house. So for example, I have the Amazon PWS skill loaded and configured to respond with the data from my home's PWS via Weather Underground - if I ask what the temperature is outside, I get the temperature right outside the door. Secondarily, my HomeAssistant home automation pulls my PWS data via Weather Underground as well, to be able to plan lawn watering and other temperature/weather related actions for all my home automation tasks.

So you didn't think that MAYBE a Low Data Hungry alternative with a Link to your site was a better alternative than cutting everyone off and pissing people off? lol wow, you could have dummied down the API to just a current temp or current condition. With a Link to your site for a real forecast. I run a server over the years and I know the data from a simple ping could not be that bad, unless your getting raped on your data service, maybe you should shop around

As a PWS data provider, I find the new API unsatisfactory as the temperature and wind speeds are lacking precision with whole numbers only. I need more precision for calculating accurate wind chill temperatures. Can you please consider adding 1 or 2 decimal places.

Hello. I work for a Fortune 100 company and we are users of the Weather Underground API. Recently, the free API stopped working and we are interested in purchasing an API key. I have filled out the Contact form twice and tried calling your sales office. After 2 weeks, I have yet to receive a response. I would like to know how to resolve this issue as this is impacting our production applications.

This is really, really sad. Even killed the old Forum credentials which you could have copied over to this forum’s login. Made us start over again.

Its not usually a good idea to upset your largest base of community developers. Wunderground is where innovation happened. It feels like you bought it and killed it. Can you at least copy over the wunderground API call syntax for hobbyists, so we don’t have to learn new and re-write all our calls to your new API? Some of us took many years to learn Wunderground’s API, and we get to start over again? Very sad. I’m so upset i’m shopping for other places to go. You seem to be badly abusing your monopoly status in he US. Hate to send my calls to one of the UK services that are still friendly to hobbyists, but I will consider it.

I may also have to stop sending my Gold-star station data every 5 seconds to a new service entirely. Like many station owners, I’ve been feeding this scientific data to wunderground for many years and never received any compensation from any of the ads on my station page. And this is the thanks we get? The only return I received from it was the ability to make calls occasionally through the API, which stayed about the same and very reliable for many years. Now we’ll be switched over to some big corporate bloated API that we probably won’t be able to get working.

The Weathee company is making hand over fist based on your accounting in your annual reports. It’s bizarre to me that one of the services you bought with the most unique batch of home weather hackers on Earth, with an increasing number of calls (not decreasing) to the API, couldn’t just be left alone and subsidized by the mother company if needed to keep your team of underground hackers on your side.

R&D takes forever to make money, and Wund is your grass-roots R&D area.l and you’re killing it

Something tells me there is some fundamental reason why you’re killing Wund. Is it because I only have the Wund App on my phone and not the TWC app? Is someoneMs ego rustled by that?

I use Wund because the page usually loads very fast and is easy to read and find things that I want to see. You should at least add a new “weather hacks” area to weather.com then, a new home for those left out in the cold by this to play and innovate. We all benefit from this. I really feel sad for universities who will have to change all their software to find data somewhere else for their research.

I predict you will lose data feeds from home stations. Maybe you don’t care. I’m a world where big data is now king, making a move to potentially lose free data doesn’t seem to make sense to me.

If anyone knows another place to move to from Wund and take my station data, please reply.

I’d also like to hear any theories about the real reason this is happening. Makes no sense that a massive company can’t keep a small innovation arm going. The PEOPLE who feed data to and experiment with Wund’s API are what matter here. And I feel youMre about to lose a lot of us.

Two imagined "real" reasons (for lack of any honest answers):COUNTERCULTURAL Funny how elitist corporate culture hates anything described as grass-roots. Consider that the title "Weather Underground" traces its origins to a counter-cultural hippie group that specialized in 1960s anti-establishment antics. As cool as that may sound to many, Weather Co. brass may find it too 'radical'.

CONSPIRATORIAL(This point is entirely hypothetical, so don't go claiming it is real, unless, of course, it is): Perhaps the underground weather junkies using this stuff might've been able to detect very early signs of a catastrophic-type natural disaster -- if the service remained status quo. Heaven forbid that "regular folks" could access a network capable of communicating factual details, advance warnings, and perhaps a window of public preparation time. Corporate elitists could have other plans. Thus, they end Wund API and its potential for truthful details to be reported by ground-level troops, and instead retain control behind a company firewall.

ydnew nine: I tend to accept your conspiratorial theory: this is the second time in the last few months that community (and therefore free) platforms will be cancelled and made available only for premium members. But this one (WU) is less acceptable.

Here, as PWS owners, we provide almost uptodate weather data of our region. Most of us with a more-or-less precise GPS data.

In this case we had to payed for the data we are providing instead threating us to pay (How many? ) if using the API afterwards.

Hi, László. I have been trying to get this message out in the forum in as many places as I can.

I understand that
these changes can be difficult
but I
want to assure you that Personal Weather Station (PWS) contributors will
continue to have complete, uninterrupted access to their own data as well as a limited range
of additional data, such as short-term forecast, through the Weather
Underground API as well as through the Wunderground web site. If you have a PWS currently reporting to us,
your access for that data is, and will be, free.

What a complete BS - you pissed off all PWS data providers by killing the website, making even uploading data impossible (the source of your frigging organization) and now that? Go down the greedy drain where you and the utterly incompetent "managers" of IBM belong. You will never, ever get any of my data again.

For several months, uploading data fails. For existing and for new accounts (the existing one was working for several years...) - there is ZERO support and with IBM's clear goal to run Wunderground into the ground and let everybody pay for accessing their data (the data that is truly the base for your business, and that is provided for FREE to you...), there is really no point to discuss anything regarding "low volume access" - what a BS. The users don't only provide "low volume" weather data for free either.You don't know about the problems - well then simply scan through YOUR OWN FORUMS... But it does not surprise me that nobody knows, simply because nobody really gives a sh.t...Taking advantage of users that supported and got wunderground where it is today (well, where it was before greedy IBM took over...) simply makes me want to puke. So much for supporting a good cause for fellow weather enthusiasts.

Terry, all I can do is offer to help. If you want me to have a tech look into a station that's not loading, I can and will. But you're not providing me with anything I can use to address the issues you're concerned about. I have personally gone through months of problems on this forum, and asked users if the issues were resolved. All the uploading issues I know about are from software not making appropriate upload calls. Dozens and dozens of people have seen my email address here and emailed me directly with problems, which have been or are being addressed. Just because it's not visible on the forum doesn't mean nothing is happening.

I understand you are disappointed in the way things have changed. I get it -- I started using WU in the late 90s when I was at the University of Michigan. But it is a ﻿business﻿.

I look people in the eye who are doing what they can to keep that spark of WU alive. They are not that cartoon character of the evil, cigar-smoking businessman that you may be imagining. They genuinely care about the PWS owners; they care about weather data.

If you want to give me some specific issue, great. Otherwise, there is nothing I can do but continue to wish you well.

Tom, I'm not going to get into debating the whole business model. I don't have access to the business's bottom line. Nor do I spend much time thinking about it. I spend all my time working with individuals on individual issues, solving problems.

U.S. current conditions data comes from 180,000+ weather stations across the country including:

Almost 2,000 Automated Surface Observation System (ASOS) stations located at airports throughout the country. These are maintained by the Federal Aviation Administration and observations are updated hourly, or more frequently when adverse weather affecting aviation occurs (low visibility, precipitation, etc).

Over 250,000 Personal Weather Stations (PWS's) that are part of Weather Underground's ever-expanding PWS network. Stations are put through strict quality controls and observations are updated as often as every 2.5 seconds.

Over 26,000 weather stations that are part of the Meteorological Assimilation Data Ingest System (MADIS) which is managed by the National Oceanic and Atmospheric Administration (NOAA). For further information, see https://madis.ncep.noaa.gov/.

So most of your data comes from either data generated by the fed or donated from PWS's.

We are a private school running a few PiClocks for weather and forecast data. We would like to set up more PiClocks in the future but without weather data, it's kinda a dead project. Will there be any API offerings for education?

Hi Brian, Someone will reach out to you shortly to review your options, We are asking customers to move to our API offerings through the weather channel. These APIs are supported by a much larger team and are much better suited for using in production systems. The downside is they tend to be more expensive.

I am working in a university with limited funding to provide agricultural weather forecasts to farmers and uploading weather data every 15 minutes from 18 sites for free to Wund so that we could get reliable 10-day forecast in our region. You are now saying that we have to pay with more expensive fee to use the new API. We just managed to set our system up properly in the last few months and now we have to start all over again and pay for it. We can afford this new paying scheme if you are going to pay us also for our uploaded data to your site, otherwise, just like everybody else feeding our precious data to you, we will find a new place for our data where we can send our data starting 01/01/2019.

Okay, Nelio, I'm not sure I understand completely. Please forgive me while I try to clarify.

If you are a current PWS (personal weather station) user/key holder, you will continue to have complete, uninterrupted access to your data as well as a limited range of additional data, such as short-term forecast, through the Weather Underground API as well as through the Wunderground web site. If you have a PWS (or many PWS's!) currently reporting to us, your access for that data is, and will be, free.

What I would like to still do is access, without a fee, the 10-day forecasts of other PWS aside aside my own (now 20 instead of 18) PWS (and counting) sending weather data to Wunderground every 15 minutes for free. I believe that uploading our data to your site for free would be enough payment for us to use the API to get forecasts from other PWS without a fee. Charge others who are just users but not contributing their PWS data to Wunderground.

Wow, Wunderground. No free developer account??? WTF? You just lost a potential customer. And I'm going to stop using you and recommending you. That's really sad. You're the first ones I thought of when I came up with a new startup idea, and using Wunderground APIs is just a non-starter now.

If your new system (marketing team?) were worth anything they would know to implement rate limiters or other means to control traffic from a free developer account, like practically every other service created by competent developers. Seriously, in 2019 **in the internet age**, you're pay-only and shunning developers like that? It's a shame.

Not that sooo special!My weather station has a "direct connection" to WU ... So I only could get the data if I star with an own DNS in my home network that makes sure that the WU traffic from that "closed" device is redirected to a server of mine or such ... So I have the topic that I want to get access to "my" data ... ideally the same "realtime" information (station sends any 3mins or such) as the station is sending so that I can also use wind data for my sun-protection controls.

Hi, yes I know the download of the past :-) This is one part I would need. I I could widh then an API where I regeister a websocket and then get data pushed once they get updated would be great. This would then be kind of "real time" and technically is not that complex. or be able to set a "Callback URL" where you actively push data to in a HTTP POST or GET call could also work.But as written the second interesting part is the "local forcast" fpor at least the next day, especially for awaited rain, temperatures and such. But this is enough to check once per hour or such.

Then one thing: It seems that my PWS was not correctly added to my WU account back then and so the PWS is not shown there. I contacted WU several times but got no answer to fix this assignment. I want to make sure to get these infos as "PWS owner" when the time has come. Who I should contact to check and fix it?

As someone who has been sending data to Weather Underground for a while, but who just recently got in a better position to use the api to pull my own data, the fact that keys are no longer available is very disappointing. I appreciate the issues that were raised, and the possibility of eventually getting access to the data I provide, but not having a timetable or a plan in place prior to cutting off new API keys isn't helpful. Hopefully we will hear something soon, but will be looking into alternatives in the meantime.

Aaron, understand the frustration, but we don't want to get into a situation where people are building things that will break in a few months as the service changes. Expect more information in october, and some examples and documentation by end of october

Hi Timreading between the lines, I sense that it has been the mis use of the free api's and WU data in ways that was never intended that has put too much strain on the server's and that is what has prompted the removal of the free api's as they are now and a move to a different system aimed at commercial customers who can afford to pay more and will, yes? (if so I can understand that, as some systems have relied on wundergrounds data as your guys expense too much)

Hi, I am a non-commercial user of the API and would like to receive updates whenever available to learn about the new plan. Can I subscribe to a mailing list to be alerted when the new plan is made available? Your API is the most accurate weather data source I could find for my budget and I'd hate for my app to suffer due to a less efficient API. Any information would be greatly appreciated, thanks!

For developers who use WU API data for non-commercial purposes, you will have access to a new plan for a personal use, low call volume API.

What about developers who use the API for commercial purposes? The new Core plan API might have what I need, but it also has way more than I need. And the fact that there's no price listed anywhere makes me think that this will be priced far beyond what I can pay. My users want to view current data from a specific station. It's a small app that I made as a hobby project in my spare time, I'm not a big business (or a business at all). I have a small but loyal user base who like the simple and quick data presentation that I provide. I make enough to cover the current API costs, but If it costs even double what the old API was, then I'm out.

Yeah, this is a ridiculously short amount of time for developers to switch. Developers should have several months to actually work with the new API before the old one is cut off (especially since new API's will probably be buggy - developers working with it early can help find those). And we don't even have API documentation yet to know if the data we actually want to get to is included or not. Before they said that access to an individual station's data was not going to be part of the new API, but now the info page for the Core plan kind of sounds like it will after all, but it's not clearly stated for sure. Maybe it's just talking about a location rather than an individual station. Weather buffs want THEIR station's data presented to them, not just for the general location.

If you are a Personal Weather Station owner, you will receive more information about our plan to offer free access to the data you provide to Weather Underground. We’ll reach out once that plan has been finalized.

So does that mean we continue sending you our data at the current rate/interval but will be restricted in our own retrieval rate? 100 calls a day is not going to cut it and if your company thinks we will pay (an undisclosed amount) Then it's time to move on again. I sense the continued way these responses are answered is intened to leave us in the dark as long as possible.

I am the author of the popular WU-forecast.php script which allows personal weather website owners to display the WU forecast for their area using the WU API key. The script is in use on several hundred websites around the world. With the upcoming discontinue of the WU API, these sites (most of them WU data contributors) will not have a forecast to display.

Will there be a free API key for the Weather.com API for low-volume use offered so I can rewrite the script for the new API? If not, I will likely have to discontinue the WU-forecast.php script (making several hundred current users quite peeved, in addition to my strong disappointment that WU continues to shed functions that have long been supported by your data contributors).

Wow, so there is no way to downgrade and you are still charging people without allowing them to cancel their subscription or downgrade? This a complete and utter disgrace. Ever since the Weather.com acquisition of this company WU has fallen apart! I will not be using NO NEW API and giving you guys a single dollar. I am done and moving my business to Aeris.

I have several PWS deployed in Guatemala, and had advocated in Latin America about WU platform for years as a way to make weather data available to more users specially in Latin America where met services lack this kind of information.

I convinced a lot of people in the region to deploy PWS's because I noted that the forecast got better after some days of data being sent, I think that the PWS network that all wx enthusiasts like us helped to built is one of the big assets that made WU appealing to TWC and then to IBM.

I understand business decisions, but as many has mentioned before, as a PWS network user and WU site user I feel all this was abandoned since these Corporate changes. The crowdsourcing model made you and all users had access to realtime data in remote location like yours and like ours in Latin America.

I just want a fair treat with a forecast API for users that has contributed to this platform (many of us for years when WU was a great startup). Just imagine how many hours in development has been invested like what saratogaWX has mentioned that must start again from 0 or loose what accomplished.

BTW, I came here via a Google search, did not received an email, all of you fellow PWS owners receive something ?

And what about commercial use cases that are relatively low volume and don't need (and cannot afford) forecasts, maps, etc, just daily station data? My 5 year old iOS app will be dead in the water if I still can't get that information for about the same cost. I make a little bit from an ad banner, but not enough to afford a huge price increase.

When can we expect prices and a beta API developers can start testing with? Time is running out, not everyone is in a position to turn around changes that fast.

Eric: >> BTW, I came here via a Google search, did not received an email, all of you fellow PWS owners receive something ?the same here. As a PWS owner I also just reading this post because a friend drew my attention to it. :( And just curious what will happen with my (btw presonnal) weather data after 01.01.2019.Probably I will stop to publish them and keep the data providing by the hardware just private. It's a pity.

As Tim Roche notes above, personal weather station (PWS) owners will not be impacted. They will have access through the keys they already have to their own data, and probably a limited range of short-term forecasts.

We're trying to get to the point of rolling out information about this publicly, it's just not quite ready yet. More to come!

Yea I use the API in my relay program to CWOP to pull airport and GPS data from WU on install. I was sent no info on this and found it by accident. I dont use forcast users requested a API and entered it in the program to pull there station status. Everything will have to be rewritten with out notice.

Also anyone know why we are nolonger allowed to delete bad data from out station page....

I do have a wepage that pulls data but rather then rewrite the code I might as well create a script to post data to my website direct. If openweather didnt have a broken unusable API I would use it.

We have done everything we can to reach API keyholders. I'm sorry we were unable to reach you.

The API will continue to function past the end of the year for PWS owner/uploaders until the new API for PWS owner/uploaders is ready. If you want a peak at the documentation for the new API, you can look here.

I am using the Wunderground service to control my garden watering sprinkler system by weather parameters. The OpenSprinkler system used is a commercial product, but it is used for non-commercial purposes. The weather parameters needed are yesterdays mean temperature, yesterdays min. and max. humidtity and yesterdays and todays precipitation summary. A 4-day weather forecast is also retrieved for convenience reasons. All this data is send to Wunderground by my own PWS via Meteoware for Netatmo and retrieved by OpenSprinkler software via my free Wunderground API key at a low call volume rate. In summary historical, current conditions, astronomy and forecast data is requested on an hourly basis.

The question is now will this service be stopped by the end of the year? Is it just a new API key? Are there changes in the API interface that need software adaptations?

How about pricing? Documentation and a usable beta is critical but none of that matters if I can’t afford the new API and I have to kill my 5+ year old iOS app. I would like to have these answers a couple months ago at the latest.
